1. Introduction Statistical process control refers to a statistical method used to separate variation produced b y special causes and varation produced by natural causes. This is done so that it is possible to eliminate the special causes and to establish and maintain consistency in the process‚ allowing the process to be improved. A Process refers to everything that is done in a workplace. Multiple factors affect these processes and they are usually refered to as the Five M’s. The Five M’s

Inspection for variables —there is typically one dimension most indicative of QUALITY or lack of Quality of an item being studied for compliance to a Quality Standard. Here it is a dimension such as the contents of a jar of fruit jam‚ the size of a pair of shoes etc. These are called X-bar and R charts. One calculates X-bar-bar and R-bar averages and these are the centre lines of the SPC run-charts that will

SCOPE This project was conduct for: • All 12 samples have to take dimension measurement every each SD card slot . • To countermeasure the defect product in order to achieve tolerance by using Statistical Process Control (SPC). • The specification is defined as an Upper Control Limit (UCL) and Lower Control Limit (LCL) value from X-bar and R-bar chart. • To identify that dimension whether

with the improvement phase of the project. Statistical Process Control is an effective method of monitoring a process through the use of control charts. It would involve using Statistical techniques to measure and analyze the variation in processes. It can detect the presence of special causes of variation. To make a chart‚ you first have to study the process and find out how what sort of results to expect. Plotting ongoing results of the process on the chart can alert you to changes that could

VIPIN R ABSTRACT Acceptance sampling may be applied where large quantizes of similar items or large batches of material being bought or are being bought or are being transferred from one part of organization to another. Unlike statistical process control where the purpose is to check production as it proceeds‚ acceptance sampling is applied to large batches of goods which have already been produced. Acceptance sampling is a method used to determine if you accept or reject a particular lot
